ffmpeg: do not finish output streams manually on eof even if no input is provided

The generic code should be able to finish the streams just fine initializing
and flushing the filters and codecs properly.

Fixes the following command:

ffmpeg -f lavfi -i "testsrc=d=0.1[out0];aevalsrc=0:d=0[out1]" -af apad -shortest -f framecrc -
